We humans like to think that we are special. But there is a group of people who believe that humans are no better than animals and as such, all creatures should be treated equal. If you want to give paid maternity leave to your cat or your seat on the LRT (light rail transit) to the visiting hippopotamus, be my guest.
But as human beings, we are held accountable by a different set of rules, yes? You may say that homosexuality is natural, but if a human being had done what this male duck did, he would be imprisoned. With a straitjacket over his prison uniform.
Apparently, it took Dr Moeliker over five years to gather up courage to report the necrophiliac homosexual rape of a male mallard (fancy name for duck) outside his office. Love how deadpan and wry his writing is (it is something I don't see in the journals I usually read, darn those dry, snooze generating stuff) and it is reflected in his presentation (see below a video presentation of Dr Moeliker on the occasion of receiving his IgNobel Prize).
Guys, I won't blame you if you feel a little inadequate; the rapist duck clocked in at 75 minutes thrust time and only stopped after the estimable Dr Moeliker interrupted his business. In between, he had rested only twice, each time lasting less than five minutes.
Sexual harrassment also exist in the animal kingdom. South African biologist Nico de Bruyn reported of an Antarctic fur seal who had (mistakenly?) mounted an adult king penguin (of unknown sex) for 45 minutes. Golly, there is just no escaping jerks like that, huh?
